my 99 years old great grandma my great grandma is 99 years old so her mind isn't clear sometimes. she thought that my dad is her husband. one night, she angrily came to my parents' bedroom, yelling to my dad "who the hell is the woman sleeping on the bed with you? i can't believe that you're really cheating on me!! we've been married for so many years. do you know how much i love you? you can't do that to me!" she was deeply hurt.
